It's tough to think about inventors without remembering dear Dr. NakaMats. He claims to have invented over 3,000 items—frequently while almost drowning himself—and basically thinks Thomas Edison's an uneducated wimp who quit at 1,093 inventions.

Aside from karaoke machines, NakaMats also claims to have invented floppy disks, a weird golf putter, compact disc players, digital watches, springy-shoes, hydrogen-powered engines, a crazy arm chair that which may or may not have made some man's cancer worse, and a lot more. Sure, there's talk that he may be a complete loon who's just spouting lies and barely invented anything, but who cares? The man's amusing on video. [Motherboard via Gizmodo]
